Oth fx upr and low end r fibula, subs for clos fx w nonunion

This code signifies a fracture of the upper or lower end of the right fibula that is not healing properly (nonunion), and the patient is presenting for follow-up care after the initial treatment. The fracture is closed, meaning the skin remains intact over the injury site.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed closed fracture of the right fibula's upper or lower end is being managed for nonunion. This includes situations where surgical intervention for nonunion is being planned or has already occurred, or when conservative management for nonunion is ongoing.

• Ensure documentation clearly states "nonunion" and specifies the right fibula's upper or lower end.
• Verify the encounter is for follow-up care, not the initial treatment of the fracture.
• Confirm the fracture is documented as "closed" to differentiate from open fractures.
